setOption

public void setOption(String option,
                      String value)

getTimeZone

public String getTimeZone()
Returns value of the TimeZone option.

activateOptions

public void activateOptions()
Description copied from interface: OptionHandler
Activate the options that were previously set with calls to option setters.

This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.

For example, the FileAppender has the File and Append options both of which are ambigous until the other is also set.

dateFormat

public void dateFormat(StringBuffer buf,
                       LoggingEvent event)

setDateFormat

public void setDateFormat(DateFormat dateFormat,
                          TimeZone timeZone)
Sets the DateFormat used to format time and date in the zone determined by timeZone.

setDateFormat

public void setDateFormat(String dateFormatType,
                          TimeZone timeZone)
Sets the DateFormat used to format date and time in the time zone determined by timeZone parameter. The DateFormat used will depend on the dateFormatType.

The recognized types are NULL_DATE_FORMAT, RELATIVE_TIME_DATE_FORMAT AbsoluteTimeDateFormat.ABS_TIME_DATE_FORMAT, AbsoluteTimeDateFormat.DATE_AND_TIME_DATE_FORMAT and AbsoluteTimeDateFormat.ISO8601_DATE_FORMAT. If the dateFormatType is not one of the above, then the argument is assumed to be a date pattern for SimpleDateFormat.
